Broken Tap Extraction Tool with Tapered Sharp-Edged Teeth for Impact Driven Tap Removal
20260084229 · 2026-03-26 ·

A tap extraction tool for extracting a broken tap from a workpiece using an accompanying impact driver. The tool features a tool body shaft with a drive end, and a working end situated distally thereof along a longitudinal axis. The working end has tapered teeth and intervening void spaces arranged around the axis. The tapered tooth geometry includes a narrowing of a circumferential tooth width to a pointed biting edge in a radially inward direction, and a narrowing of a radial tooth thickness in the longitudinally distal direction. Two inner faces of the working tooth convergently intersect at the biting edge, which angles outwardly away from the central longitudinal axis in the longitudinally distal direction. The circumferential tooth width also narrows in a radially inward direction, from two non-parallel and convergently angled outside edges of an outer circumferential surface of the tooth.
